Summary
Diabetes significantly increases atherosclerosis risk in India, with millions affected. This review examines key factors like hyperglycemia and insulin resistance accelerating this process in diabetic patients, leading to worse coronary artery disease outcomes.
Area of Science:
- Cardiology
- Endocrinology
- Public Health
Background:
- Diabetes mellitus affects over 20 million people in India, projected to reach 57 million by 2025.
- Diabetic patients face a heightened risk of atherosclerosis and its complications, notably coronary artery disease (CAD).
- CAD is the leading cause of mortality in diabetic populations.
Purpose of the Study:
- To review the multifactorial role of various risk factors in accelerating atherosclerosis in diabetic patients.
- To highlight the mechanisms by which diabetes promotes cardiovascular complications.
Main Methods:
- Literature review focusing on pathophysiological processes.
- Analysis of risk factors contributing to accelerated atherosclerosis in diabetes.
Main Results:
- Hyperglycemia, insulin resistance, dyslipidemia, oxidative stress, hypertension, and altered fibrinolysis accelerate atherosclerosis in diabetics.
- These factors destabilize atherosclerotic plaques, leading to premature clinical events.
- Diabetic patients exhibit a worse prognosis for CAD compared to non-diabetics.
Conclusions:
- Diabetes significantly exacerbates atherosclerosis through multiple metabolic and hemodynamic pathways.
- Understanding these risk factors is crucial for managing CAD in diabetic patients.
- Early intervention targeting these factors may improve cardiovascular outcomes in diabetes.
